I. ADCs for Electricity Metering: The Core of Precise Power Data Acquisition

Electricity metering ADCs are specialised analogue-to-digital conversion chips developed by ADI for specific applications within the power sector. They are primarily designed for smart meters, power grid quality monitoring, industrial energy consumption management and power terminal data acquisition. Unlike general-purpose ADCs, this category of chip eliminates redundant features to focus on the core requirements of power signal acquisition. With synchronous sampling, wide-temperature stability, high-precision harmonic measurement, high integration and strong immunity to interference as its key advantages, it serves as the cornerstone of hardware for intelligent power metering.

1. Key Technical Features

Electricity metering ADCs predominantly utilise a Σ-Δ modulation architecture and possess multi-channel synchronous sampling capabilities, enabling the precise acquisition of power parameters such as grid voltage, current, power, harmonics and reactive power losses. The chips incorporate a high-precision reference voltage source, a programmable gain amplifier and a dedicated metering DSP core, eliminating the need for additional peripheral processing circuits and significantly simplifying the hardware design of power equipment. They are also designed to meet the stringent operational requirements of the power industry, supporting a wide operating temperature range of –40°C to +125°C and possessing exceptional electromagnetic interference immunity, enabling long-term stable operation in complex grid environments. Furthermore, these chips maintain constant accuracy across a wide load range, ensuring high-precision metering under both light and heavy load conditions, and meeting the high-precision electricity meter certification standards of State Grid and China Southern Power Grid.

2. Leading Models

Smart single-phase/three-phase electricity meters, high-precision power grid quality analysers, energy consumption monitoring terminals for industrial power distribution cabinets, metering equipment for grid-connected photovoltaic and wind power systems, energy metering modules for electric vehicle charging points, and power Internet of Things (IoT) data acquisition terminals.

II. High-Speed ADCs: The Flagship for High-Frequency Dynamic Signal Acquisition

High-speed ADCs are high-performance conversion chips developed by ADI for high-frequency, transient and dynamic analogue signal acquisition scenarios. Their core advantages lie in ultra-high sampling rates, wide bandwidth and high-speed data throughput. They primarily address the industry pain point where general-purpose ADCs are unable to capture high-frequency oscillations, transient pulses and RF signals, and serve as core components in communications, radar and high-frequency test equipment.

1. Key Technical Characteristics

High-speed ADCs predominantly utilise a pipelined architecture. Unlike the low-speed characteristics of SAR and Σ-Δ architectures, this enables parallel, high-speed signal conversion. Sampling rates range from 10 MSPS to over 1 GSPS, with resolution typically centred on 12 to 14 bits, striking a balance between sampling speed and fundamental accuracy. The product range encompasses three major series—high-to-mid-frequency, low-to-mid-frequency and ultra-wideband—enabling the acquisition of high-frequency signals across different frequency bands. Supporting high-speed serial data interfaces, these devices feature low latency, high bandwidth and low jitter, enabling the precise capture of dynamically changing signals without signal distortion or sampling delay. Furthermore, the chips feature high integration, with built-in clock buffers and reference circuits, simplifying the hardware matching design for high-frequency systems.

2. Leading Model Series

ADI’s high-speed ADC product portfolio is comprehensive: the high- and medium-frequency series covers 10 MSPS to 125 MSPS, suitable for intermediate frequency (IF) signal acquisition; the low- and medium-frequency series covers 125 MSPS to 1 GSPS, meeting RF-to-IF conversion requirements; and the ultra-wideband series exceeds 1 GSPS, suitable for ultra-high-frequency signal acquisition. Classic models are suitable for mainstream applications such as software-defined radio, 5G RF front-ends and radar signal acquisition.

3. Core Application Scenarios

5G/6G RF communication equipment, software-defined radio, radar detection systems, ultrasonic non-destructive testing, high-frequency vibration monitoring, high-speed image scanning, aerospace transient signal acquisition, and high-end oscilloscopes and spectrum analysers.

III. Precision ADCs: The Benchmark for High-Precision Measurement of Low-Speed, Static Signals

Precision ADCs are ADI’s flagship products in the field of high-precision measurement, characterised by ultra-high resolution, extremely low noise, high linearity and minimal temperature drift. They are primarily designed for the precise acquisition of low-speed, static and weak analogue signals. Rather than prioritising ultra-high sampling rates, they are optimised to deliver the utmost in conversion accuracy and stability, making them core components for industrial precision measurement and control, instrumentation and sensor data acquisition.

1. Key Technical Characteristics

Precision ADCs feature a diverse range of architectures, covering the two mainstream types: SAR (Successive Approximation Register) and Σ-Δ (Sigma-Delta) integration. Resolution spans the full range from 8-bit to 32-bit, with the capability to achieve ultra-high-precision 32-bit conversion. The chips exhibit extremely low offset error, gain error and temperature drift coefficients, coupled with exceptional noise immunity, enabling the precise capture of faint sensor signals in the millivolt and microvolt ranges. The Σ-Δ precision ADCs are suitable for ultra-low-speed, high-precision static acquisition, whilst the SAR precision ADCs balance moderate sampling rates with high precision to meet the requirements of various precision measurement scenarios. They also support multi-channel synchronous sampling and a wide input voltage range, making them suitable for the acquisition of all types of precision sensor signals.
